When I use on my new 01781 canner the pressure reads 14 PSI. Is it safe to assume the guage is off by 1 psi?

One pound of pressure difference isn't going to affect the temperature in your cooker by enough to do harm. Thirteen, fourteen, or fifteen pounds of pressure will work equally well, so the reading doesn't make a lot of difference in any case.

I would ask if you are at high elevation, as per the canning books by Ball describe. I am at sea level but can get my gauge to go up and down as I need.

I just wrote that mine was off by a pound. the instructs say to have it calibrated by local cornell cooperative but don't think they still do it (can always check in your area). If you are going for 15 pounds and it reads 14 but the regulator is jiggling, I'd assume it's fine.

PH, I assume that you are at an elevation wher 15 pounds is needed so to answer your question, it is yes. That is why experts advise having their pressure gauge tested every year or so. Using the weight, there is no need to be concerned if the gauge is off a bit. Although 1 psi would not be critical, the rules have always been strictly black and white with no gray area between.

It may be. You should follow the manufacturer instructions an have the valve checked at your local county extension office. Also I noticed the pressure valve picture shown is the model 50332 which does not come up as a replacement valve for this model. Although the same weight you should use the recommended valve for your cooker which in this case is the 09978.

this depends on the manufacture date of your canner. Mine takes the thicker gasket but I am not sure which part number is thicker. I have the wrong one currently.

I don't think this pressure cooker is more than 10psi. I use a large canner with a gauge that goes up to 20psi. Highest recommended psi is 15psi. I have used 10 psi for almost everything and I find the cooking time comparable to that. Only way to know for sure, ask the manufacturer.

I don't know. I have never used these Jars in a pressure canner as I did not purchase them for that. I would not use them for that purpose, as I use them for storage. Sorry that is not much help!

Hi Karen,One thing I found out is that other pressure cookers have a PSI of 15 and the Instant Pot is only 11. So I have been adding extra time to most recipes and everything has been turning out alright.

You will need the model number of your canner which should be in the book that came with it or it is located on the canner itself either on the bottom or located under one of the handles . Once you have this information finding the correct seal is easy

Not sure what the specs say. I have no problem with mine on a Dewalt with 175 psi tank pressure.

I was going to write to contact Presto directly, but others answered it does. I bought it because I wanted to compare it to the regulator included with my 23-quart canner. was within 1 pound. agree that it is most handy for when needing to can at 5 or 10 pounds

I prefer pressure canners that do not have gauges. Gauges must be tested yearly. The rockers do not. Just check the manufacturer's instructions for rate of rocking.

hi there. there is no 15psi. its 12 psi for the 2 setting and 7psi for the 1 setting. i then add a few minutes to the cooking time for a 15psi need. it really isnt that big a difference and you will get the same results. promise. I love my pressure cooker to death and use it for everything from whole octopus to potatoes. mmm

I operated it at 90 psi and had no problems..not sure what manual reads do not have time to look it up

the cooker comes with 2 flat round weights with a center hole. When 1 is used (placed over the indicator) it signifies 5lbs. of pressure, when the second one is added over the top of the first one it signifies 10lbs. of pressure. Just off the top of my head, could be 5 & 15lbs. instead of 10lbs. If accuracy is premier, I would imagine a pressure gauge could be bought, but I couldn't swear to it.

Depends how old it is and what brand and if it is for canning or a regular pressure cooker. Let me know and I will see if I can help.

I was surprised by this post so I went to the USDA web site and was refered on to the Natinal Center for Home food Preservation I copied this straight out of the Canning Tomatoes section "Use of a pressure canner will result in higher quality and more nutritious canned tomato products. If your pressure canner cannot be operated above 15 PSI, select a process time at a lower pressure.

I would get a 0-30 psi gauge. It would be more accurate for a low pressure reading.

This cooker does not have a gauge showing PSI and you cannot build up pressure and then start timing. It is too small for canning jars. I have a 7 qt pressure canner that works great.

I believe the gauge goes to 30 Psi but the pressure you need depends on your altitude and recipe and i think most recipes call for 15psi.
